QUAD
An MPI program to estimate an integral

QUAD is a program which estimates an integral over [0,1].

A typical approach would be to divide the interval [0,1] into P subintervals, and have each process produce an estimate for its subinterval.

This program, instead, takes N evenly spaced values in [0,1], and then assigns them in alternating order to the processes. If there were two processes, then process 0 would be getting all the odd numbered points, and process 1 the evens, for instance.

Source Code:

• quad.c, the C source code.
• quad.cc, the C++ source code.
• quad.f, the FORTRAN77 source code.
• quad.f90, the FORTRAN90 source code.

Scripts:

• quad.sh, a script for running the program.
